My invention has relation more "specin callyto a wallfmold constructionof the slip form type for forming .hollow` concrete walls andsimultaneously forming a plurality of concrete bonds between the wallmembers to tie the same together. i

Vlin-order ,to providev for the proper placement of the'metal bonds during thewall pouring operation, relatively Ylongladderswcarrying metal bonding rods were required to be set inpositionprior to the operati-on of pouring the wall members, this procedure notvonly entailing consider able trouble but increasing the cost of erecf:tion. f f i f In the present invention such ladders or supportszforInetalbonding rods. are dis- Other ob'ects and advantages will beapparent from vthe following specification, references being had rto theaccompanying` drawings forming 'a part thereof, in which: Fig. 1 Vis atransverse vertical section of l the slip form mold in connection with ahollow concretewall construction. f Fig. 2 is a detail perspective viewof the ylower portion of the mold orm,illustrating the meansA employedin formingthe concrete CII Wallbondng membrs- ,Fig. 3 .is av.perspective view of a portion of afinishedV hollow Wall, Showing theconcrete rbonds connecting the wall' me`1n- `bers. l' f" Fg- 4' isaPartialplan View 0f al .hllow conoretewall partly in section togetherwith the mold forms.

` `Vv` The bonding` 'members 491D hS Case which kserve to Atiefthe twowallmembers together are formed wholly of concrete, als

though metal reinforcing rods may be introduced thereinifthoughtdesirable, and are preferably formed' in spaced vertical rows and adista-nce apart equal to the length of the core boxes `19, as clearlyshown in Fig. 3. yEach of the four vertical edges 41 of the coreboxes'a're grooved for the reception of wood slide plates 42, and it isthought the infethodof forming `the, bonds may be more readilyunderstoodby a description in connection with Figs.v 6V to 9 inclusiveyof the drawings.v In Fig.v 6, the movable slipform is illustrated inposition at the foundation 30 Vof thewall members, in this position slipboards 42 are iirstplaced in the corner grooves ofthe oppositelydisposed ends of two adjacent 4core boxes 19, 'the height of 1. theseboard are approximately o-ne half of the height'of tlieyb'oxes.v Crossboards 43, .are then laid across the upper ends of boards 42, their endsproj ecting'slightly beyond the side lfaces of the core boxes, see Fig.2. Concrete is then poured between the mold forms to a height just abovethe boards43, (see Fig.y 7) Vand metal reinforcing rods 44 may 'be thenintroducedV ifdesired.l After the sainerhave been placed in positionother slip boards 45 exactly similar toy boards 42l are s inserted inthe corner grooves of the core vboxes, their lower ends being disposedabove 4the crossboards 43 a distance equal to the ydesired thickness ofthe bond. The pouring of concrete in the moldsis'again resumed as v'shown in Fig. 8, the wet concrete pouring throughthe openings formed bythe cross boards 43 andthe lower ends of the slide 'boards 45 andforming a complete concrete bond between lthe wall members.

After the above described operations are lcompleted the slip forms aremoved up' reassess wardly to the position shown in Fig. 9, when pvothercross boards 43 rare again laidfacross the upper ends of the lowerslide boards 42, asy described and shown in Fig. 6. The above operationsare Vcontinued until the en# tire wall members have been poured, theconcrete bonds 40 being foi-'med at regular intervals as shown in Fig.3. f yIt will be understood that when the forms are moved upwardly inorder. to add to the heightof the wall members, the slip boards 42 willbe held against movement byV their adhesion to the inner faces of theformed' wall members, but if found desirable they may be knocked out ofplace after the'walls have been formed. 1 c Y It will be readilyapparent from ,the above description that by the employment of coreboxes in a slip form construction and spacing the abutting endsin spacedrelation, in combination with side slipboards and cross boards thatlconcrete'bonds maybe formed at regular intervals between the two wallmembers asthe lconcrete is poured, the bonds as effectively tyingythe'walls members together as the metal bonds ontlie rods in thepatented structure hereinbefore referred to'. lWhat lclaim is: 'y Y LAconcrete mold form` comprising a movable mold form consisting of aplurality of walls spaced apart to form moldcavities adapted to beutilized in the formation of a pair of hollow wall members, and meansconnected to some of said mold forniwalls and removable therewithforforming a plurality of concrete bonding members adapted to connect ortie the wall members together as the same are poured'.
